When you need this tape, having it ready to use on the spot is the best way to go.
I have used it for lots of things and it works great.
I even used it to repair a big hole in my car exhaust 3 years ago and it is still holding today.
It was easy to do and It was perfectly inspect-able.

Isermal Silicone Rubber Self-fusing Tape a must have for all toolboxes!
